Update for the most up-to-date list of supported processors for these boards.
The D850MD and D850MV boards support a single Pentium 4 processor (in a 478-pin socket)
with a system bus of 400 MHz. The D850MD and D850MV boards support the processors listed
in Table 5. All supported onboard memory can be cached, up to the cachability limit of the
processor. See the processor’s data sheet for cachability limits.

Type Designation System Bus L2 Cache Size
Pentium 4 processor Up to 2.0 GHz 400 MHz 256 KB
CAUTION
Use only an ATX12V-compliant power supply with the D850MD and D850MV boards. ATX12V
power supplies have two power leads that provide required supplemental power for the Intel
Pentium
4
processor and the Intel 850 chipset. Always connect the 20-pin and 4-pin leads of the
ATX12V power supply to the corresponding connectors on the D850MD and D850MV boards.
Otherwise, the board and the processor could be damaged.
Do not use a standard ATX power supply. Doing so could damage the board and the processor.
